Various methods for managing interference handling overhead are provided. One example method includes generating interference overload indication information and causing the interference overload information to be transmitted on a broadcast channel for relay nodes, wherein the transmission via the broadcast channel indicates that the interference overload indication information is for a donor cell. Similar and related example methods and example apparatuses are also provided. Additional example methods and apparatuses are also provided.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method comprising: generating, using a processor, interference overload indication information, wherein generating interference overload indication information includes generating interference overload indication information at a donor cell; and causing the interference overload indication information to be transmitted on a broadcast channel for relay nodes, wherein the transmission via the broadcast channel indicates that the interference overload indication information is for the donor cell without the interference overload indication information comprising an identifier of the donor cell, wherein the donor cell supports at least one relay node by establishing a backhaul interface with the respective relay node.
2. The method of claim 1 , wherein generating interference overload indication information includes generating interference overload information, the interference overload information indicating an inter-cell interference level experienced by the donor cell.
3. The method of claim 1 , wherein causing the interference overload information to be transmitted on the broadcast channel for relay nodes includes causing the interference overload information to be transmitted on relay node control channel of the backhaul interface.
4. The method of claim 1 , wherein causing the interference overload information to be transmitted on the broadcast channel for relay nodes includes causing the interference overload information to be transmitted in a predefined backhaul link sub-frame.
5. The method of claim 1 , wherein causing the interference overload information to be transmitted on the broadcast channel for relay nodes includes causing the interference overload information to be transmitted on a relay-physical broadcasting channel (R-PBCH) between a relay node and the donor cell.
6. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, direct the apparatus at least to: generate interference overload indication information, wherein generating interference overload indication information includes generating interference overload indication information at a donor cell; and cause the interference overload indication information to be transmitted on a broadcast channel for relay nodes, wherein the transmission via the broadcast channel indicates that the interference overload indication information is for the donor cell without the interference overload indication information comprising an identifier of the donor cell, wherein the donor cell supports at least one relay node by establishing a backhaul interface with the respective relay node.
7. The apparatus of claim 6 , wherein the apparatus directed to generate interference overload indication information includes being directed to generate interference overload information, the interference overload information indicating an inter-cell interference level experienced by the donor cell.
8. The apparatus of claim 6 , wherein the apparatus directed to cause the interference overload information to be transmitted on the broadcast channel for relay nodes includes being directed to cause the interference overload information to be transmitted on relay node control channel of the backhaul interface.
9. The apparatus of claim 6 , wherein the apparatus directed to cause the interference overload information to be transmitted on the broadcast channel for relay nodes includes being directed to cause the interference overload information to be transmitted in a predefined backhaul link sub-frame.
10. The apparatus of claim 6 , wherein the apparatus directed to cause the interference overload information to be transmitted on the broadcast channel for relay nodes includes being directed to cause the interference overload information to be transmitted on a relay-physical broadcasting channel (R-PBCH) between a relay node and the donor cell.
11. A computer program product comprising at least one non-transitory computer-readable storage medium having executable computer-readable program code instructions stored therein, the computer-readable program code instructions being configured to: generate interference overload indication information, wherein generating interference overload indication information includes generating interference overload indication information at a donor cell; and cause the interference overload indication information to be transmitted on a broadcast channel for relay nodes, wherein the transmission via the broadcast channel indicates that the interference overload indication information is for the donor cell without the interference overload indication information comprising an identifier of the donor cell, wherein the donor cell supports at least one relay node by establishing a backhaul interface with the respective relay node.
12. The computer program product of claim 11 , wherein the computer-readable program code instructions are configured to generate interference overload indication information are further configured to direct the apparatus to generate interference overload information, the interference overload information indicating an inter-cell interference level experienced by the donor cell.
13. The computer program product of claim 11 , wherein the computer-readable program code instructions are configured to cause the interference overload information to be transmitted on the broadcast channel for relay nodes are further configured to direct the apparatus to cause the interference overload information to be transmitted on relay node control channel of the backhaul interface.
14. The computer program product of claim 11 , wherein the computer-readable program code instructions are configured to cause the interference overload information to be transmitted on the broadcast channel for relay nodes are further configured to direct the apparatus to cause the interference overload information to be transmitted in a predefined backhaul link sub-frame.
15. The computer program product of claim 11 , wherein the computer-readable program code instructions are configured to cause the interference overload information to be transmitted on the broadcast channel for relay nodes are further configured to direct the apparatus to cause the interference overload information to be transmitted on a relay-physical broadcasting channel (R-PBCH) between a relay node and the donor cell.
